和大神们学习每天一题(leetcode)-Palindrome Partitioning

Given a string s, partition s such that every substring of the partition is a palindrome.

Return all possible palindrome partitioning of s.

For example, given s = "aab",
Return

[
    ["aa","b"],
    ["a","a","b"]
  ]

功能测试用例："aab";"aabbaacdc"

特殊测试用例："a","aa","aaa"
